Top 5 Projects Are Using The Optimism OP Stack
The OP Stack, or Optimism stack, is a collection of open-source software components that powers the Optimism network and its ecosystem. It is maintained by the Optimism Collective, a large and well-funded community.
The OP Stack includes modules that are chosen based on their utility, simplicity, and extensibility. A module must: Help power the Optimism Collective; Be simple and understandable to enable scalability and reduce engineering costs; and be extensible so that it can be used to build with and on top of.
The OP Stack is decentralized, meaning that any user can access and contribute to the codebase. The OP Stack aims to create a shared, high-quality, and fully open-source system for deploying new rollup networks. This is especially important with the advent of the Superchain concept, which requires new networks to be created securely and to interoperate with each other. By coordinating on shared standards, the Optimism Collective can avoid rebuilding the same software repeatedly.
While the OP Stack currently simplifies the process of creating layer 2 blockchains, it is not limited to this. The OP Stack also extends to layers on top of the underlying blockchain, including tools like block explorers, message-passing mechanisms, and governance systems.
What is the OP Stack?
Empowering the Optimism network and its comprehensive infrastructure, the OP stack, or optimism stack, is a compilation of software elements currently constituting the backbone of the Optimism mainnet. Managed by the well-resourced Optimism Collective, this stack outlines the various components within the Optimism setup. As per the Optimism team, these components are chosen based on their utility, simplicity, and ability to be expanded upon. Any new addition to the stack is expected to contribute to the strengthening of the Optimism Collective, be user-friendly to facilitate scalability and minimize development expenses, as well as adaptable to ensure its potential for further development. The software itself operates in a decentralized and open-source manner, allowing any user to access and contribute to the underlying codebase.
The principal objective of the OP Stack is to establish a shared, top-notch, and entirely open-source framework for deploying new rollup networks. This becomes particularly crucial with the introduction of the Superchain concept, which necessitates the secure establishment of new networks that can seamlessly interact within the proposed Superchain environment. By adhering to common standards, the Optimism Collective can prevent redundant development efforts in isolated environments. While the current focus of the OP Stack is streamlining the creation of layer 2 blockchains, its scope extends beyond this. The OP Stack encompasses layers above the foundational blockchain, encompassing tools like block explorers, message-passing mechanisms, governance systems, and more.
OP Stack is in its initial Bedrock phase, representing the first implementation of the stack. Bedrock equips users with the necessary tools to launch optimistic rollup networks, with its APIs tailored specifically to support these rollups. This release has been tailored to accommodate the Optimism Superchain, which envisions a network of interconnected layer 2s sharing security features, communication layers, and the common development stack (the OP Stack itself). Bedrock facilitates swift creation and deployment of custom rollup networks that seamlessly integrate into the Superchain ecosystem. However, it should be noted that, as of the Bedrock release, the OP Stack isn’t designed for adaptability, a key feature for tailoring rollup networks, which will become essential for the upcoming iterations of the OP Stack.
Structure of the OP Stack
Ethereum functions as the dedicated Data Availability (DA) layer for the OP Stack, with data from the sequencer module formatted and directly published to Ethereum. The integrity of the entire OP Stack relies on the security of the data stored on Ethereum, facilitated by its Proof of Stake (PoS) consensus mechanism. Ethereum, in its capacity as a DA layer, not only stores data but also ensures that all blocks are entirely accessible to network participants, a process overseen by participants who download and verify block contents. Future plans involve the implementation of data structures and DA assurances outlined in EIP-4844, including Binary Large Objects (BLOBs) and Data Availability Sampling (DAS), once Ethereum’s rollup-centric roadmap is completed.
At present, the OP Stack operates using a single Optimism sequencer module that gathers and publishes transaction data from the execution layer to the DA layer. This sequencer module verifies valid transactions, creates batches, and submits them to the base layer, forming the backbone of the rollup. As part of their vision for a decentralized rollup network, Optimism intends to introduce a modular sequencer set, facilitating the integration of multiple rollup networks within the OP Stack. This sequencer set allows OP Stack-based chains to bypass developing their own sequencer and enables atomic cross-chain composability with other chains.
The Ethereum Virtual Machine (EVM) serves as the dedicated module for the execution layer of the OP Stack, processing inputs from the derivation layer to execute state changes. As the OP Stack’s implementation of the EVM is minimally modified to support layer 2 transactions initiated on Ethereum, the state structure of OP Stack-based chains remains fully compatible with other EVM-based protocols, enabling seamless redeployment of smart contracts and accelerating the development of native ecosystems.
The derivation layer provides data inputs for state writes, determining how raw data from the DA layer is formatted and processed for the execution layer. Currently achieved through a rollup module, the plan is to replace this module with an indexer module that performs similar functions when events occur on specified smart contracts within the base layer.
The settlement layer serves as a read-only mechanism for external blockchains, allowing them to access the state of an OP Stack chain and make decisions accordingly. Presently, settlement is established using an attestation-based fault-proof mechanism, leveraging optimistic fraud proofs. Proposed settlement modules, including fault-proof optimistic settlement and validity proof settlement, aim to enhance the settlement process using permissionless fault-proving and zero-knowledge proofs, respectively.
Lastly, the governance layer, consisting of various modules, manages the OP Stack by overseeing system configuration, upgrades, and design decisions. Governance tokens and multisignature smart contracts are utilized for governance, with tokens representing voting power in decentralized governance models, and multisignature smart contracts executing decisions upon reaching a predefined threshold of signatures from participants. These decisions are often influenced by votes conducted using governance tokens.
The OP Stack currently drives the Optimism network, offering a layered architecture that serves as an effective framework for constructing secure, scalable, and integrated rollup networks. Each layer performs a critical function and is managed by specific networks or components, collectively providing the necessary functionality to build a comprehensive rollup network within an interoperable OP Stack-based ecosystem.
